MP SERIES: INSTALLATION & OPERATION MANUAL
PAGE 2
The inDESIGN MP30 – 30 watt, all-in-one mixer amplier is
designed for small to medium installations where multiple
playback sources are required. The in-built FM Tuner & USB/SD
MP3 player allow easy playback of your favourite FM station,
or music stored on a USB drive or SD card.
The MP30 delivers 30 watts via 8Ω or constant voltage 100V
and 70V speaker outputs and features 2 Microphone/Line
inputs with individual gain control for external audio sources
and microphones.
The MP series feature 2 Mic/Line inputs. The MP Series provide
either 4 Ohm or constant voltage 100V speaker outputs. A ‘pre-
amp out/power amp in’ link allows for the mixer audio signal to
be sent to an external equaliser or a booster amplier.

IMPORTANT SAFETY INSTRUCTIONS
1. Read these instructions.
2. Keep these instructions.
3. Heed all warnings.
4. Follow all instructions.
5. To prevent injury please refer to these instructions for electrical and safety information before installing
or operating the apparatus.
6. No naked ame sources such as lighted candles should be placed on the apparatus.
7. Operation of this apparatus is recommended for moderate climates only.
8. This apparatus must not be exposed to dripping or splashing liquid.
No object lled with liquid, such as a vase, should be placed on the apparatus.
9. Clean only with a dry cloth.

11. Do not install near any heat sources such as radiators, heaters, stoves, or other apparatuses
(including ampliers) that produce heat.
12. Unplug this apparatus during lightening storms or when not in use for long periods of time.
13. Protective Earthing Terminal:
The apparatus should be connected to a mains socket outlet with a protective earthing connection.
14. The mains plug/appliance coupler is used as a disconnect device, the disconnect device shall remain
readily operable.
15. When not in use and during transportation, please take care of the power cord set, for example, tie up
the power cord set with a cable tie/something similar. It should be kept away from sharp edges and
the like that can cause abrasion of the power cord set. When put into use again, check that the power
cord set is not damaged. If any damage is found, have the unit checked by a qualied service person
to replace the power cord set specied by the manufacturer.
16. The terminals marked with symbol of “ “ may be of sufcient magnitude to constitute a risk of
electric shock. The external wiring connected to the terminals requires installation by a qualied service
person or the use of ready-made leads or cords.
17. Only use attachments/accessories specied by the manufacturer.
18. Check speaker line load prior to connecting to amplier using an impedance meter.
19. Refer all servicing to qualied service personnel. Servicing is required if the apparatus has been
damaged in any way, such as power-supply cord or plug breakage, damage due to liquid or objects
falling onto the apparatus, exposure to rain or moisture, or if the apparatus does not operate normally,
or has been dropped.
20. Correct Disposal of this Product:
This marking indicates that this product should not be disposed of with other household wastes. To
prevent possible harm to the environment or human health from uncontrolled waste disposal, recycle
it responsibly to promote the sustainable reuse of material resources. To return your used device, please
use the return and collection systems or contact the retailer where the product was purchased. They
can take this product for environmental-safe recycling.
WARNING: There are no user serviceable parts inside. Refer all servicing to qualied service personnel.

You must allow a minimum 10 cm or 4 inches of unobstructed clearance around the unit.
Do not place the unit on a bed, sofa, rug, or similar surface that could block the ventilation openings. If the
unit is placed in a bookcase or cabinet, there must be ventilation of the cabinet to allow proper cooling.

To calculate the ampliers capability:
If your chosen amplier has a maximum output of 30 Watts at 100V,
the minimum impedance connected should be at least 333 Ohm (100V x 100V/333 Ohm = 30W).
Use a professional impedance meter, not a Multimeter.
INSTALLATION
How to Calculate the correct load for a 100V Amplier:
When installing a 100V loudspeaker system, it is rather simple to calculate the number of loudspeakers that
can be connected to a particular 100V amplier.
Each 100V loudspeaker has a 100V transformer that will have different power tappings, for example 1.5, 3
and 6W. The sum of all taps should never exceed the ampliers power rating.

1. Power Switch: Turns mains power on and off.
The round LED light surrounding the Master Volume control indicates the unit is on/off.
2. Mode button: Press repeatedly to cycle through USB/SD/MMC/FM radio or Bluetooth media playback
(Bluetooth mode automatically searches for external device; refer to your BT device manual for setup
instructions).
3. Transport buttons: Play/Pause, Stop, Repeat/Loop, Previous and Next track buttons
(which also select FM stations).
4. USB input: For playback of MP3 and WMA audio les (not suitable for charging media devices).
5. SD/MMC card slot: For playback of MP3 and WMA audio les on suitable media.
6. Input 1 & Input 2: The selected Microphone or Line input level is controlled via these knobs.
7. Treble: Adjust the level to suit the required tone of the output. Increasing the treble may improve
intelligibility, decreasing the treble may reduce the onset of high frequency feedback.
8. Bass: Adjust the Bass level to suit the required tone of the output. Increasing Bass may make music sound
fuller, reducing the Bass in reverberant spaces may improve speech intelligibility.
9. Media level: Adjust the volume of media section to suit the environment and use of the system.
10. Master level: Adjust the overall system volume to suit the environment and use of the system.

11. Mains Socket: The unit is connected to the mains circuit with a standard IEC type power lead. This socket
contains a rated slow blow fuse.
**NOTE: Only use a fuse equal to the marked rating.
12. Loudspeaker Outputs:
When connecting low impedance loudspeakers use the COM and 8Ω connections. For 70V and/or
100V loudspeakers use the COM and 70V or 100V connections.
For 70V or 100V operation, the total minimum impedance of the loudspeaker lines should not
overload the amplier. Refer to the above installation guide for how to calculate the loudspeaker
load or measure with an impedance meter.
Use only one of the loudspeaker connections. Do not combine both 8Ω and 70V/100V
loudspeaker connections.
13. Pre-Out/Main-In: If required the output signal can be sent from the pre-amplier of the mixer to an
external device such as an equaliser or processor and the processed signal can be fed back into the
amplier via the Main-In connection. If this feature is not used ensure the RCA link is connected across
the Pre-Out/Main-In. If this link is lost the unit will not pass audio signals connected to the unit.
14. Input 1 & 2 Mic/Line: These microphone inputs The Vox level pot sets the threshold of the internal Priority
Mute level. Microphone 1 input can mute all other inputs. The input selector switch is used to choose
between the Microphone or Line input. The Microphone input can be connected to either the 3-pin XLR.
The line input can be connected to the Dual RCA inputs. The Dual RCA is internally summed for mono.
15. Antennae sockets: for FM radio and Bluetooth.
